*The script we use in QC can be found on the Share drive here: S:\Digital Projects\Administrative\scripts\qc\ filenamesAndDupes.pl

*After you have corrected the errors, RUN THE SCRIPT AGAIN. If the script still finds errors, correct those and run it again. Keep running the script until it does not show any more errors.

Pass the collection to a coworker so he or she can go through the process again (as the Second QC Check).

A second person goes through the exact same steps listed above. If errors are found, the team member who did the initial capture should be informed, so he or she can fix them. Those materials should then be put through the QC cycle again. The cycle can be repeated as many times as necessary, until the Second QC Check uncovers no errors or problems.

+

This Recheck takes place in the Completed folder, and the content should have been prepped for upload, according to the instructions in [Preparing_Collections_on_the_S_Drive_for_Online_Delivery_and_Storage]. Verify that all necessary files are there, named correctly, and that the folder structure is correct as well.

+

+

Please follow the folder renaming process outlined in [[Scans_folder]]. This means that if there are problems with images in Scans_Recheck_4, then you document those problems (in an email; cc a supervisor if there's a large quantity of problems or issues -- or serious, or recurring ones, as retraining may be necessary).

+

Then re-label that image directory as Scans_Check_4 to indicate that it has been returned for repairs to the person who performed the captures. It will need to be rechecked again once the repairs have been made.

+

+

Remember: results of scripts must be clear, and all content completely approved, before you can relabel the directory as Scans_QCed_# (appropriate number in place of the #) and clear the content for upload.

If everything is hunky-dory, please congratulate the person who performed the work on doing a GREAT job (and tell the supervisor! We love to hear this, and it will be reflected on their annual reviews!) and rename the folder Scans_QCed_# (appropriate number in place of the #), and tell the person responsible to go ahead with uploads.

Revision as of 10:07, 17 October 2012

The Quality Control (QC) process is iterative, and involves at least 2 staff members.

The person whose digitization is being checked performs the first round of QC: run the QC script and make repairs, rerunning it until there are no errors; and THEN do a capture-by-capture review (images: an eyeball check; audio: an auditory check). For both types of material, check metadata item numbers against the items themselves.

Do *not* wait until you have hours of QC to do, because after the first hour, you will make mistakes. This is time consuming and very detail oriented.

After the first round of QC, when you think you have it perfect, pass it to a coworker, who will go through the same process but who will give YOU the feedback to make all the repairs. Continue this cycle until the results are perfect in the view of both team members.

See Scans_folder for instructions on relabeling the Scans folder to show its progress through QC.

QC Check

Throughout this process, please follow the folder renaming process outlined in Scans_folder.

QC Script

The script we use in QC can be found on the Share drive here: S:\Digital Projects\Administrative\scripts\qc\ filenamesAndDupes.pl

This program will check for correct and sequential filenames per the collection number in a Scans folder and its corresponding Transcripts folder (if there is one) as well as check for duplicate filenames. It will print out a report in the “output” folder.

If it shows errors, please rename the files accordingly and also check the metadata and trackingFiles to make sure the filename is OK in those spreadsheets. When you are done with the report file this script created, please delete it.

After you have corrected the errors, RUN THE SCRIPT AGAIN. If the script still finds errors, correct those and run it again. Keep running the script until it does not show any more errors.

You should be able to run this program by double clicking on it. You might need to associate the file type with Perl the first time you use it.

Visual Spot Check

Once you've run the programs and fixed any problems, please check images.

Open every object folder with Adobe Bridge.

Verify what you see against what's in the Metadata and the number of scans recorded on Tracking files.

If you are working on a collection in collaboration with someone else or are working on an ongoing collection, mark the items that have been QCed on the QC tab of the Tracking Files sheet.

Prep for upload

Follow the preparation for upload processes as outlined in [Preparing_Collections_on_the_S_Drive_for_Online_Delivery_and_Storage]. The person performing the recheck for your quality control work is to ALSO verify that these folders are set up properly, and that all necessary files are there and named correctly, before upload scripts are run.

Hand-off

Pass the collection to a coworker so he or she can go through the process again (as the Second QC Check).

Second QC Check

A second person goes through the exact same steps listed above. If errors are found, the team member who did the initial capture should be informed, so he or she can fix them. Those materials should then be put through the QC cycle again. The cycle can be repeated as many times as necessary, until the Second QC Check uncovers no errors or problems.

This Recheck takes place in the Completed folder, and the content should have been prepped for upload, according to the instructions in [Preparing_Collections_on_the_S_Drive_for_Online_Delivery_and_Storage]. Verify that all necessary files are there, named correctly, and that the folder structure is correct as well.

Please follow the folder renaming process outlined in Scans_folder. This means that if there are problems with images in Scans_Recheck_4, then you document those problems (in an email; cc a supervisor if there's a large quantity of problems or issues -- or serious, or recurring ones, as retraining may be necessary).
Then re-label that image directory as Scans_Check_4 to indicate that it has been returned for repairs to the person who performed the captures. It will need to be rechecked again once the repairs have been made.

Remember: results of scripts must be clear, and all content completely approved, before you can relabel the directory as Scans_QCed_# (appropriate number in place of the #) and clear the content for upload.

If everything is hunky-dory, please congratulate the person who performed the work on doing a GREAT job (and tell the supervisor! We love to hear this, and it will be reflected on their annual reviews!) and rename the folder Scans_QCed_# (appropriate number in place of the #), and tell the person responsible to go ahead with uploads.
